DontFlushMe is a notification system that allows New Yorkers to take sewage overflow into their own hands (and we mean that in the least disgusting way possible). We first met DontFlushMe’s inventor Leif Percifield when he introduced the system to us, and now he’s come up with a new sensor and Visualight Wi-Fi light bulb capable of notifying users by lighting up whenever there is an overflow in the sewers. The nifty and useful little gadget will also be available to the public as a perk from his Kickstarter campaign.
